We provides five kinds of spheric lens forms, or shapes, that determine the imaging Characteristics of the lenses, they are plano-convex, plano-concave ,Double-convex, Double-concave and Meniscus.
· Plano-convex lens has a positive focal length, which makes it ideal for collecting and focusing light for many imaging applications..
· Plano-concave lens has a negative focal length and is used for image reductinon or to spread light.
· Double-convex lens has a positive focal length and is useful for 1:1 imaging and in multielement systems. also known as biconvex or equiconvex.
· Double-concave lens has a negative focal length and is useful for 1:1 imaging and in multielement systems. also known as biconcave or equiconcave.
· Meniscus lense has a positive or negative focal length, it forms a real or virtual image of objects.
